    ** http://info.webcrawler.com/mak/projects/robots/norobots.html holds what
    ** many people consider the official web exclusion rules.  Unfortunately,
    ** the rules are not consistent about how records are formed.  One line
    ** states "the file consists of one or more records separated by one or more
    ** blank lines" while another states "the record starts with one or more User-agent
    ** lines, followed by one or more Disallow lines."
    **
    ** So, does a blank line after a User-agent line end a record?  The spec is
    ** unclear on this matter.  If the next legal line afer the blank line is
    ** a Disallow line, the blank line should most likely be ignored.  But what
    ** if the next line is another User-agent line?  For example:
    **
    ** User-agent: MooBot
    **
    ** User-agent: CreepySpider
    ** Disallow: /cgi-bin
    **
    ** One interpretation (based on blank lines termination records) is that MooBot
    ** may visit any location (since there are no Disallows for it).  Another
    ** interpretation (based on records needing both User-agent and Disallow lines)
    ** is that MooBot may not visit /cgi-bin
    **
    ** While poking around, I found at least one site (www.sun.com) that uses blank
    ** lines within records.  Because of that, I have decided to rely on records
    ** having both User-agent and Disallow lines (the second interpretation above).
